A duck walks into a 7/11, and asks, “Do you have any grapes?” the guy behind the counter says, “No,” and the duck leaves. The next day the duck walks back in and asks, “Got any grapes?” the guy behind the counter, starting to get frustrated says, “Like I told you yesterday, we don’t have any grapes, we don’t sell grapes, and never will.” The next day the duck walks in and says, “Got any grapes?” the guy behind the counter yells, “No, I told you before we don’t sell any fucking grapes, if you come in here and ask for grapes again, I’ll nail your feet to the floor.” The next day the duck walks in and says, “Do you have any nails?” the guy behind the counter says, “no.” Duck says, “Then do you have any grapes?”
